As the smartphone screens get bigger and bigger , the battery drain increases, but now Arman Ahnood, a researcher at the London Centre for Nanotechnology, has an elegant solution: smartphone screens with built-in solar cells Read more »
Researchers Create ‘Sun-Believable’ Solar Cell Paint
Notre Dame researchers have created a semiconductive paste, which can turn surfaces its applied to into solar cells. A team of researchers, lead by Professor Prashant Kamat, created the new material by coating nano-sized particles of titanium dioxide with either cadmium sulfide or cadmium selenide, and then suspending them in a water-alcohol mixture to create a paste. The paste can then be applied to a transparent conducting material, which creates electricity when exposed to light. Read more »
